Custom Language Support
IntelliJ Platform is a powerful platform for building development tools targeting any language. Most of IDE features consist of language-independent and language-specific parts, and you can support a particular feature for your language with a small amount of effort: you just need to implement the language-specific part, and the language-independent part is provided for you by the platform.
This part of the documentation will explain the main concepts of the Language API and will guide you through the sequence of steps which are usually required to develop a custom language plugin. You can obtain additional information about the Language API from the JavaDoc comments for the Language API classes and from the source code of the Properties language support, which is part of the IntelliJ IDEA Community Edition source code.
